App release Code Sign error on xcode

Question

I tried to build release version of my project for my iPHone device. (I choose Products->Archive), then I got the following error:

Code Sign error: The identity 'iPhone Distribution: XXX' doesn't match any valid, non-expired certificate/private key pair in your keychains

What does it mean & How to get rid of this problem?

By the way, I opened my keychain access, and found this iphone Distribution: xxx under " certificates ", it is not expired.

I googled the problem, someone said it is because my app bundle id does not match the one defined in provision file. But how can I check the bundle id defined in provision file?

Answer 1

Go to Project->target->Build settings, change your code signing identity for release. Do the same in Project->Build settings-> Codesigning. Then clean the build and build it again.

If it is not working, close the project and open it again and build it. it will work.
